The LockWrite combines two most frequently used police tools (a pen and a handcuff key) into a single design. The result is a functional pen that has been married to a durable heat treated ASP handcuff key.

The core of the LockWrite is a precision, high density ink cartridge from Germany. Each LockWrite is packaged with a spare ink refill. The handcuff key of the LockWrite is produced from 4140 steel, the same alloy we use in ASP Batons. A matte black body is accented in Silver.
